Fusion Call Con trol Handler
See Figure 3-96 wh en mul t ipl e nu mbers o f F CH circuit cards are connect ed t o a 24 D T R as a cascade c on-
necti o n . The FCH can be com b i n ed w i t h CCH/D CH o n a c as cade connection.
One D TI card can have a ma xim um o f five (5) Hand ler c ircuits c asca ded w ithin the FCH card, th e CC H
card, and/or DCH card. Since the FCH card contains one Handler circuit per card, a maximum of five (5)
FCH cards can be ca sc ad ed to a DTI card.
As an exa mp l e, th e f o llowing (a), (b) a nd (c) can co ex i st on a casca de connec tion.
(a) FCH card (One ( 1 ) Handler circu it card per card)
(b) CCH card (T w o (2 ) Handl er circuits p er card)
(c) DCH card (Two (2) Handler circuits per card)
Also, you must consider the cascading cable length. (Note)
Figure 3-96 FCH Cascade Connection
Note: A maximum cable distance between DTI and the last cascaded FCH (or CCH/DCH) is 50 cm (1 7.6 ).
